InterviewSolution

1.	If `f, g, h`are real functions given by `f(x)=x^2,g (x)=tanx a n d h(x)=log, x , t h e n`write the value of `(hog of)(sqrt(pi/4))dot`
Answer» Correct Answer - A `{h o(g o f)}(x) =(h o g){f(x)}=(h o g) (x^(2))` `=h{g(x^(2))}= h (tan x^(2)) = " log (tan "x^(2)")"` `:. {h o (g o f)} .sqrt((pi)/(4))= "log " (tan .(pi)/(4))= " log " 1=0`
